strabismus
Pronunciation: /strəˈbɪzməs/
Misalignment of the eyes where the visual axes do not intersect at the fixation point.
Full Definition
Strabismus is a condition characterized by misalignment of the eyes, where one eye deviates from proper alignment while the other maintains fixation. The deviation can be horizontal (esotropia or exotropia), vertical (hypertropia or hypotropia), or torsional (cyclotropia). Strabismus may be constant or intermittent, alternating or unilateral, and can result from muscle weakness, nerve palsy, refractive errors, or central nervous system disorders. Beyond cosmetic concerns, untreated strabismus can lead to amblyopia, loss of binocular vision, and reduced depth perception, making early diagnosis and treatment crucial.
Usage
Usage note: Specify the type and degree of deviation; 'squint' is acceptable in patient education contexts.
